I think they did an awesome job on the special effects and costumes. The kid's acting was very good. The person who played Lucy is so young but she did as good as the older kids. The special effects looked very hard to do. Aslan looked like a real lion. All the animals in narnia are done wonderfully. The costumes looked perfect too. The girls' outfits looked harder but thats just my opinion. The people who made this movie defiantly took their time because it's one of my favorites!
